Abstract

L'invention concerne une méthode de traitement de mesures brutes collectées par des bolomètres d'un détecteur, la méthode comprenant : a) un calcul de termes masqués, le calcul consistant à retrancher à la mesure brute de chaque bolomètre masqué d'une colonne donnée, la valeur moyenne des mesures brutes des bolomètres masqués de ladite colonne ; b) une corrélation entre les termes masqués et des composantes calibrées des bolomètres masqués déterminées selon la relation : les termes étant des mesures de référence des bolomètres masquées obtenues à une température de référence et en masquant le détecteur avec un masque ; c)une étape correction de l'image brute qui comprend le calcul de mesures corrigées d'une image corrigée pour chaque bolomètre sur la base du résultat de l'étape b) de corrélation.The invention relates to a method of processing raw measurements collected by bolometers of a detector, the method comprising: a) a calculation of masked terms, the calculation consisting in subtracting from the raw measurement of each masked bolometer of a given column , the average value of the raw measurements of the masked bolometers of said column; b) a correlation between the masked terms and calibrated components of the masked bolometers determined according to the relation: the terms being reference measurements of the masked bolometers obtained at a reference temperature and by masking the detector with a mask; c) a raw image correction step which comprises the calculation of corrected measurements of a corrected image for each bolometer on the basis of the result of the correlation step b).
